AUGUST 'WARTH, OF GALVESTON, TEXAS.

HUB-ATTACHING DEViCE.

SPECIFICATION forming part of Letters Patent No. 249,809, dated November 22, 1881.

Application filed September 5, 1881. (No model.)

To all whom it may concern Be it known that I, AUGUST WAR'rH, a citizen of the United States of America, residing at Galveston, in the county of Galveston and State of Texas, have invented certain new and useful Improvementsin Axles and Boxes for Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom-- panying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention has relation to improvements in axles and boxes for road-vehicles and it has for its objects to provide a eheap,:simple, and reliable means of fastening a vehicle-wheel to an axle, and which will be easy of application and adjustment, will hold a lubricating agent, and exclude foreign substances from the intorior.

My invention consists in the novel construction and arrangement of the parts, as will be hereinafter set forth and specifically claimed.

In the accompanying drawings, Figure 1 is a longitudinal sectional view. Fig. 2 is an end view, showing the ring in place. Fig. 3 is a perspective view of the spindle; and Fig. 4 is a perspective view of the screw-threaded sleeve or collar.

The several parts of my improvements are illustrated in the drawings, wherein- The letter A represents the end of the axle, formed with a tapering spindle, a, shoulder a, straight circular bearing 1), screw-thread c, and butting-ring d, substantially as shown in Figs. 1 and 3 of the drawings.

The letter B represents the screw-threaded sleeve or collar, corresponding in lateral measurement and in internal diameter to the screwthreaded portion of the spindle over which it is designed to fit. This sleeve or collar is formed with an annular flan ge, e, circular bearin g f, and th e part g,intended to afford wrench-gripe space when being screwed in place on the spindle or while removing it. The annular flange fits in the open end of the axle-box, and the bearing f corresponds with the opening in the ring which is secured to the face of the box.

The letter 0 represents the axle-box, having the outer end solid and interior configuration corresponding with the form of the spindle, but having the tapering portion a little longer than the tapering portion of the spindle, in order to afford achamber to retain lubricating material. The spindle is formed with a longitudinal groove, h, which acts as a distributer of oil. The axle-box at-the open end is formed with an annular wall, 0', corresponding in depth to the width of the annular flange of the screwthreaded sleeve, over which flange it fits and around which it revolves.

The letter D represents the abutting cap or ring, formed with a central circular hole, It, corresponding in diameter to the diameter of the bearing f of the screw-threaded sleeve, the exterior diameter of the ring being the same as the exterior diameter of the open end of the axle-box. This cap or ring is secured to the axle-box by screws strong enough to serve the purpose. The exterior of the axle-box has the usual ears to prevent displacement of the hub.

To apply my improvements in use, the screwthreaded sleeve is put in its place in the box and the cap screwed in its place to the open end of the box, when the wheel is put on over the spindle, and the screw threaded sleeve screwed on the spindle, and the device is ready for use. Oil or other lubricating material is applied to the spindle and run in the box before putting the wheel in place. The screwthreads in each axle-spindle are cut running toward the draft, so that the screw-threaded nuts will not be disturbed or loosened by the movements of the vehicle in its forward movement.

It will be observed that by means of the lateral groove in the tapering spindle, in connection with the chamber between the end of the box and the end of the spindle, the oil is retained and economically distributed over the spindle and parts.

The device is easily and readily adjusted, and being simple in construction, it is efficient and durable.

By reference to Fig. 1 of the drawings it will be seen that the screw-threaded collar B is adjusted on the screw-threads of the spindle a so that its outer end will fit snugly against the abutting-collar d, and the annular flange 0 will fit within the annular wall 2 of the axle-box O,

when adjusted on the axle, and that the ring D fits over the bearingfof the sleeve B, and is made secure to the annular wall 11 by fasteningscrews. By this construction and organization of parts it will be impossible for dust and other foreign matter to pass into the lubricatingchamber from the outside,for the reason that the substance has to move horizontally and then vertically, and then again horizontally and vertically, before reaching the lubricatingsurface of the axle, and then it will be again arrested by the depression in the axle-box and the shoulder a in the axle.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of a solid axle formed with shoulder d and screw-threads e, axle box 0, closed atits outer end and provided at the other end with an annular wall, 0', a collar, B, formed with internal screw-threads, annular flange e, bearing-surface f, and wrench-gripe surfaces, and a cap or ring,D, said parts being arranged and connected substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUST WARTH.
